Mario 64 - No joke. The first 2 levels were nice, but as soon as I played the sea level I actually didn't want to play it any further.
Star Trek: Voyager: Elite Force - I hate the f*ckin Borgs. They scared the hell outta me in that game.
I felt the same way with Mario 64 DS. But now everytime I play, I get a severe headache. I think its the controls or the camera.
